This engineering report describes a multiple output evaluation board designed using TOP245P. The specification chosen is targeted towards new Set Top Box systems that incorporate a hard disk. These systems require a peak power capability when the hard disk is first spun-up.
Peak power operation requires magnetics and diodes specified to handle the currents at the specified peak power point. If peak power operation is not required, designing the supply for maximum continuous power will save additional cost.
The document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and measured performance data from the prototype unit shown in Figure 1.
This report describes a design for a multiple output power supply, such as required for a Set Top Box, featuring the following:
• Very high full power efficiency (> 83% at full power)
• 32W Continuous power rating
• <0.5W no-load consumption
• Efficiency >75% at 10% output power
• Small DIL08 package for TOP245P requiring no external heatsink
• 50W peak power capability allows for high peak output power demands (e.g. for hard disk spin-up)
• Low EMI (Meets EN55022 with output ground connected to Earth)
